Any graphing utility will work. On the TI-84, a useful setting is to input the function, pressing Window to set xMin and xMax. Then pressing Zoom 0: Fit |will choose corresponding yMin and y Max to show all of the curve's important behavior. Example 6) You are given a function and an x-interval to view it.
